Qualitätsorientierter Entwurf von Anwendungsdiensten

Um die mit dienstorientierten Architekturen verknüpften Ziele wie bspw. eine höhere Flexibilität erreichen zu können, wird von Diensten die Einhaltung bestimmter Qualitätseigenschaften wie bspw. loser Kopplung oder Autonomie gefordert. Die Arbeit zeigt daher ein systematisches Vorgehen für einen Entwurf von Diensten, das durch Bestimmung formalisierter Qualitätseigenschaften und gezielter Überarbeitung in Dienstentwürfen mit gewünschten Qualitätseigenschaften resultiert

A Model-Driven Approach for Monitoring Business Performance in Web Service Compositions

Abstract — Supporting business services through Web service compositions (WSC) as part of service-oriented architectures (SOA) involves business performance monitoring requirements. Their implementation results in additional development activities. To support these activities, we already contributed a model-driven approach to the development of monitored WSC as part of our preliminary work. In this paper, we present an extension to this approach, which focuses on supporting the specification and transformation of indicators to an executable implementation. To reduce development effort for this particular task, we provide a template-based mechanism for defining performance indicators. In combination with our preliminary work, now fully monitored WSC can be generated automatically from platformindependent design models. We demonstrate the applicability of the overall approach by instantiating an integrated development process for a target platform based on IBM SOA products and showing its application for a sample business process along with monitoring requirements

Carbon tetrachloride depresses hepatic phospholipid synthesis in rats

40 h after an acute dose of CCl4 (11.3 mmol/kg), the incorporation of [1-3H]ethanolamine into rat hepatic microsomal phospholipids was inhibited to 70% of control. Incorporation into phospholipids of the inner and outer mitochondrial membranes was 30-35% of control. Rates of incorporation were equal to or above normal rates in all membranes 65 h after dosage. The activity of methyltransferase in microsomal fractions isolated from rats 10 to 66 h after dosage was depressed. These data suggest that the alteration of mitochondrial phospholipids that parallels mitochondrial dysfunction after acute CCl4 dosage could be attributed to a CCl4-induced inhibition of the microsomal phospholipid biosynthetic pathways.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/25820/1/0000383.pd

A New Sensor System for Accurate 3D Surface Measurements and Modeling of Underwater Objects

Featured Application A potential application of the work is the underwater 3D inspection of industrial structures, such as oil and gas pipelines, offshore wind turbine foundations, or anchor chains. Abstract A new underwater 3D scanning device based on structured illumination and designed for continuous capture of object data in motion for deep sea inspection applications is introduced. The sensor permanently captures 3D data of the inspected surface and generates a 3D surface model in real time. Sensor velocities up to 0.7 m/s are directly compensated while capturing camera images for the 3D reconstruction pipeline. The accuracy results of static measurements of special specimens in a water basin with clear water show the high accuracy potential of the scanner in the sub-millimeter range. Measurement examples with a moving sensor show the significance of the proposed motion compensation and the ability to generate a 3D model by merging individual scans. Future application tests in offshore environments will show the practical potential of the sensor for the desired inspection tasks

Increase in Soybean Cyst Nematode Virulence and Reproduction on Resistant Soybean Varieties in Iowa From 2001 to 2015 and the Effects on Soybean Yields

Management of the soybean cyst nematode (SCN) relies heavily on use of SCN-resistant soybean varieties to limit nematode reproduction and minimize yield loss. For Iowa, almost all SCNresistant soybean varieties contain SCN resistance genes from a breeding line named Plant Introduction (PI) 88788. Iowa State University conducts experiments to evaluate numerous SCNresistant and three to four SCN-susceptible soybean varieties in up to nine field experiments across Iowa each year. Data on SCN population density, virulence (SCN race and HG type), soybean yield, precipitation, and growing degree days frommore than 25,000 fourrow plots in field experiments conducted from 2001 to 2015 were analyzed to determine how these factors affected SCN reproduction and yield. SCN population densities were positively correlated with temperatures and negatively associated with precipitation during the growing seasons, indicating that SCN reproduction was greatest in hot, dry years. Over the years, virulence of SCN populations on PI 88788 increased in the fields in which the experiments were conducted, resulting in increased end-of-season SCN population densities and reduced yields of SCN-resistant soybean varieties with the PI 88788 source of resistance. These results indicate that soybean yield loss caused by SCN on resistant varieties with the common PI 88788 source of resistance likely will increase as virulence of SCN populations increases unless new sources of resistance become widely available and used in the future

Soil Bacteria and Fungi Respond on Different Spatial Scales to Invasion by the Legume Lespedeza cuneata

The spatial scale on which microbial communities respond to plant invasions may provide important clues as to the nature of potential invader–microbe interactions. Lespedeza cuneata (Dum. Cours.) G. Don is an invasive legume that may benefit from associations with mycorrhizal fungi; however, it has also been suggested that the plant is allelopathic and may alter the soil chemistry of invaded sites through secondary metabolites in its root exudates or litter. Thus, L. cuneata invasion may interact with soil microorganisms on a variety of scales. We investigated L. cuneata-related changes to soil bacterial and fungal communities at two spatial scales using multiple sites from across its invaded N. American range. Using whole-community DNA fingerprinting, we characterized microbial community variation at the scale of entire invaded sites and at the scale of individual plants. Based on permutational multivariate analysis of variance, soil bacterial communities in heavily invaded sites were significantly different from those of uninvaded sites, but bacteria did not show any evidence of responding at very local scales around individual plants. In contrast, soil fungi did not change significantly at the scale of entire sites, but there were significant differences between fungal communities of native versus exotic plants within particular sites. The differential scaling of bacterial and fungal responses indicates that L. cuneata interacts differently with soil bacteria and soil fungi, and these microorganisms may play very different roles in the invasion process of this plant
